Soyuz 8 (Russian:Союз 8,Union 8) was part of an October, 1969, joint mission withSoyuz 6 andSoyuz 7 that saw threeSoyuz spacecraft in orbit together at the same time, carrying a total of sevencosmonauts.
The crew consisted of commanderVladimir Shatalov and flight engineerAleksei Yeliseyev, whose mission was to dock with Soyuz 7 and transfer crew, as theSoyuz 4 (involving, among others, these two cosmonauts) andSoyuz 5 missions did. Soyuz 6 was to film the operation from nearby.
However, this objective was not achieved due to equipment failures. Soviet sources were later to claim that no docking had been intended,[citation needed] but this seems unlikely, given the docking adapters carried by the spacecraft, and the fact that both Shatalov and Yeliseyev were veterans of the previous successful docking mission. This was the last time that the Soviet-crewed Moon landing hardware was tested in orbit, and the failure seems to have been one of the final nails in the coffin of the programme.
The radio call sign of the spacecraft wasGranit, meaningGranite. This word is apparently used as the name of a reactive or defensive squadron in Soviet military training, and, just like theSoyuz 5, it was constructed and its crew was trained to be the responsive (not entirely passive) or female spacecraft in its docking. Giving military names to the spacecraft was probably a response to an appeal that the commander of the Soyuz 5 made. Further, the word was probably chosen as it begins with a letter following that sequence starting withAntey (meaningAntaeus) andBuran (meaningBlizzard);Г (G) is the fourth letter of theRussian alphabet.

The mission objectives included:[2]
Stable two-way radio communication was maintained between the spaceships and the ground stations, and TV coverage was broadcast from the ships during flight. Soyuz 8 was a part of the group flight of Soyuz 6, 7, and 8, and resembled Soyuz 6 in that it was an active ship designed to move toward the passive Soyuz 7. Soyuz 8 was equipped with full docking apparatus and for some hours flew very close to Soyuz 7. No docking occurred. The flight was safely terminated inKazakh Steppe, inKazakhstan.[2]
